描述量子电子输运的散射矩阵方法

Scattering matrix approach to the description of quantum electron transport

G. B. Lesovik, I. A. Sadovskyy

摘要:

我们考虑散射矩阵方法的量子电子输运在介观和纳米导体。这种方法是更传统的动力学方程和格林函数方法的替代方案,并且对于相干导体(特别是用于证明一般关系)通常更有效,并且通常更透明。我们提供了一个描述的时间平均的数量(例如,电流-电压特性)和电流波动的时间-噪声,以及在有限的时间内的电荷传输的完整的计数统计。除了一般的导体外,我们还考虑与超导体和约瑟夫森结的接触。

英文摘要:

We consider the scattering matrix approach to quantum electron transport in meso- and nano-conductors. This approach is an alternative to the more conventional kinetic equation and Green's function approaches, and often is more efficient for coherent conductors (especially for proving general relations) and typically more transparent. We provide a description of both time-averaged quantities (for example, current-voltage characteristics) and current fluctuations in time -- noise, as well as full counting statistics of charge transport in a finite time. In addition to normal conductors, we consider contacts with superconductors and Josephson junctions.
